【摘要】：都匀市位于贵州省中南部,地质构造发育,地质环境条件复杂,地质灾害频发,造成了巨大经济损失,严重威胁着都匀市人民群众的生命财产安全。因此,建立一个高效的、科学的地质灾害信息管理系统对都匀市地质灾害防治工作具有重要的意义。本文是在全面掌握都匀市地质灾害数据调查情况的基础上,建立地质灾害易发程度分区评价的指标体系,运用Logistic模型进行地质灾害易发程度分区。在都匀市地质灾害危险性分区结果的基础上采用ArcGIS平台建立了都匀市地质灾害信息管理系统,实现了对地质灾害空间数据与属性数据的一体化管理、快速查询、信息共享。研究的主要工作和成果如下:(1)根据都匀市的自然地理与地质环境,初步形成了一套基于数据采集与分析、评价指标选取与量化、评价模型建立与分析、危险性区划结果的确定,较为完整的区域地质灾害危险性评价的技术路线和工作流程。该研究对区域地质灾害灾情评估和防治工作有着指导性作用,为区域地质灾害防治与治理提供可靠度较高的定量依据。(2)通过概念模型、逻辑模型、物理模型对都匀市地质灾害数据库进行设计,减少了数据冗余,优化了数据结构;同时基于Oracle创建了都匀市地质灾害数据库,利用ArcSDE搭建数据通路,使得空间数据与业务属性数据统一入库,提高了数据管理的效率。(3)采用Ajax、ArcGIS Server ADF CallBack、iBATIS和.Net反射技术建立了都匀市地质灾害信息管理系统,使以前零乱的、分散的地质灾害相关资料变成了全面的、系统的、动态的信息,有利于信息在各个部门之间的交流与共享。系统的建立为地质灾害的防治与治理提供了完整的数据资料,为突发的地质灾害事故的方案制定提供了及时的信息。
[Abstract]:Duyun City is located in the central and southern part of Guizhou Province. The geological structure is developed, the geological environment conditions are complex and geological disasters occur frequently, which has caused huge economic losses and seriously threatened the lives and property safety of the people in Duyun City. Therefore, the establishment of an efficient and scientific geological hazard information management system is of great significance to the prevention and control of geological hazards in Duyun City. Based on the comprehensive understanding of geological hazard data investigation in Duyun City, this paper establishes an index system for the zoning evaluation of geological hazard vulnerability, and uses Logistic model to partition the geological hazard vulnerability degree. Based on the results of geological hazard zoning in Duyun City, the information management system of geological hazard in Duyun city is established by using ArcGIS platform. The integrated management of spatial data and attribute data of geological hazards is realized, and the information is shared quickly. The main work and results of the study are as follows: (1) according to the natural geography and geological environment of Duyun City, a set of data collection and analysis, evaluation index selection and quantification, evaluation model establishment and analysis, and the determination of dangerous regionalization results have been preliminarily formed. The technical route and work flow of regional geological hazard risk assessment are relatively complete. The study has a guiding effect on the assessment and prevention of regional geological hazards, and provides a high reliability quantitative basis for the prevention and management of regional geological hazards through conceptual model and logical model. The physical model designs the geological hazard database of Duyun city, reduces the data redundancy and optimizes the data structure. At the same time, based on Oracle, the geological hazard database of Duyun city is created, and the data path is built by using ArcSDE. The spatial data and business attribute data are unified into the database, and the efficiency of data management is improved.) the geological hazard information management system of Duyun city is established by using Ajax-ArcGIS Server ADF CallBackiBATIS and .Net reflection technology, which makes the geological hazard information management system in Duyun city chaotic. The scattered geological hazard information becomes comprehensive, systematic and dynamic information, which is beneficial to the exchange and sharing of information among different departments. The establishment of the system provides complete data for the prevention and control of geological hazards, and provides timely information for the formulation of sudden geological disasters and accidents.
